BRIEF SUMMARY OF THE INVENTION

1. Technical Field

This invention relates to aqueous emulsion copolymers which may be included in aqueous air drying latex paints in order to improve the rheology of the paint.

2. Background of the Invention

Aqueous latex paints are in common use, and these paints are frequently applied by brush. It has long been desired to include materials in the paint which will function to improve the brush drag and leveling which are obtained. While reference has been made to paint application by brushing, it will be understood that essentially the same problems effect roller application.

Brush drag is the resistance to motion of the brush as it is drawn across the surface to be painted. Aqueous latex paints are frequently too fluid, and low viscosity paints offer little resistance to brush motion. The result is that the applied coating is too thin, and insufficient paint is applied to cover and hide the surface being painted. Brush drag is improved when the viscosity under the sharing force imposed by the moving brush is increased. With greater brush drag, a greater thickness of paint is applied, and the surface being painted is thus properly covered.

Leveling is the capacity of a paint to flow out and provide a smooth and level surface. When a film of paint is brushed onto a surface with sufficient viscosity to apply a paint layer of proper thickness, the fibers in the brush leave ridges in the applied film. If the paint is too viscous, these ridges remain in the applied film as it dries, and the resulting solid paint film is not smooth and level, as is desired.

As will be evident, one needs increased viscosity to provide adequate brush drag to apply a paint film of proper thickness. At the same time, one needs decreased viscosity in order that the brush marks will flow out and disappear as the applied paint film dries. These apparently opposite characteristics exist under different conditions, the brush drag at high shear and the leveling at low shear. This raises the prospect that both may be improved at the same time.

DISCLOSURE OF THE INVENTION

In accordance with this invention, an aqueous emulsion copolymer is prepared by the copolymerization in aqueous emulsion of monoethylenically unsaturated monomers which provide a copolymer having a glass transition temperature below about 30° C., preferably below about 20° C. and which include from about 0.1 weight % or less to about 10 weight % or greater, preferably from about 1 to 5 weight %, of one or more monoethylenically unsaturated macromonomers.

The macromonomers useful in this invention can be represented by the formula: ##STR1## wherein: R¹ is a monovalent residue of a substituted or unsubstituted complex hydrophobe compound;

each R² is the same or different and is a substituted or unsubstituted divalent hydrocarbon residue;

R³ is a substituted or unsubstituted divalent hydrocarbon residue;

R⁴, R⁵ and R⁶ are the same or different and are hydrogen or a substituted or unsubstituted monovalent hydrocarbon residue; and

z is a value of 0 or greater.

DETAILED DESCRIPTION

This invention can provide aqueous latex paints with improved brush drags, especially in combination with improved leveling. These paints can be used to adequately cover a substrate with a single application and will flow out to conceal application irregularities, and this will take place regardless of how the paint is applied, e.g., by brush or by roller.

Referring to the general formulae (i) and (ii) above, it is appreciated that when R₁, R₂, R₇ and/or R₈ are a hydrocarbon residue of formulae (iii) above, the resulting compound may include any permissible number and combination of hydrophobic groups of the dendritic or cascading type. Such compounds included in the above general formulae should be easily ascertainable by one skilled in the art. Illustrative complex hydrophobe compounds having at least one active hydrogen useful in this invention and processes for preparation thereof are disclosed in copending U.S. Patent Application Serial No. (D-17008), which is incorporated herein by reference.

In a preferred embodiment of this invention, the structure shown in formula (iii) can be a residue of the reaction product between epichlorohydrin and an alcohol, including those alcohols whose residues can be described by formula (iii), or a phenolic, or a mixture thereof. The structures which result can be described as complex hydrophobes of a dendritic or of a cascading nature. Pictorially, they can be described as shown below: ##STR5##

Preferred macromonomer compounds of this invention include those represented by the formulae: ##STR6## wherein R¹, R², R⁴, R₁₉, z and j are as defined herein.

The macromonomer compounds produced by the processes of this invention can undergo further reaction(s) to afford desired derivatives thereof. Such permissible derivatization reactions can be carried out in accordance with conventional procedures known in the art. Illustrative derivatization reactions include, for example, esterification, etherification, alkoxylation, amination, alkylation, hydrogenation, dehydrogenation, reduction, acylation, condensation, carboxylation, oxidation, silylation and the like, including permissible combinations thereof. This invention is not intended to be limited in any manner by the permissible derivatization reactions or permissible derivatives of macromonomer compounds.

More particularly, the hydroxyl-terminated macromonomer compounds of this invention can undergo any of the known reactions of hydroxyl groups illustrative of which are reactions with acyl halides to form esters; with ammonia, a nitrile, or hydrogen cyanide to form amines; with alkyl acid sulfates to form disulfates; with carboxylic acids and acid anhydrides to form esters and polyesters; with alkali metals to form salts; with ketenes to form esters; with acid anhydrides to form carboxylic acids; with oxygen to form aldehydes and carboxylic acids; ring-opening reactions with lactones, tetrahydrofuran; dehydrogenation to form aldehydes, isocyanates to form urethanes, and the like.

The monoethylenically unsaturated macromonomer is subject to considerably variation within the formula presented previously. The essence of the macromonomer is a complex hydrophobe carrying a polyethoxylate chain (which may include some polypropoxylate groups) and which is terminated with at least one hydroxy group. When the hydroxy-terminated polyethoxylate complex hydrophobe used herein is reacted with a monoethylenically unsaturated monoisocyanate, for example, the result is a monoethylenically unsaturated urethane in which a complex hydrophobe polyethoxylate structure is associated with a copolymerizable monoethylenic group via a urethane linkage.

The monoethylenically unsaturated compound used to provide the monoethylenically unsaturated macromoner is subject to wide variation. Any compolymerizable unsaturation may be employed, such as acrylate and methacrylate unsaturation. One may also use allylic unsaturation, as provided by allyl alcohol. These, preferably in the form of a hydroxy-functional derivative, as is obtained by reacting C₂ -C₄ monoepoxide, like ethylene oxide, propylene oxide or butylene oxide, with acrylic or methacrylic acid to form a hydroxy ester, are reacted in equimolar proportions with an organic compound, such as toluene diisocyanate or isophorone diisocyanate. The preferred monoethylenic monoisocyanate is styryl, as in alpha, alpha-dimethyl-m-isopropenyl benzyl isocyanate. Other suitable organic compounds include, for example, monoethylenically unsaturated esters, ethers, amides, ureas, anhydrides, other urethanes and the like.

The copolymers which are modified herein provide a continuous film and are well known. These are usually copolymers of methyl methacrylate with enough butyl acrylate to provide the desired glass transition temperature, or of vinyl acetate with enough lower alkyl acrylate or methacrylate to provide the desired glass transition temperature, such as n-butyl acrylate or methacrylate, or of vinyl acetate with enough ethylene to provide the desired glass transition temperature. Other useful co-monomers such as styrene, alkyl maleates, alkyl fumarates, and esters of versatic acid may also be used.

Examples of suitable latex paint compositions include those based on resins or binders of acrylonitrile, copolymers of acrylonitrile wherein the comonomer is a diene like isoprene, butadiene or chloroprene, homopolymers of styrene, homopolymers and copolymers of vinyl halide resins such as vinyl chloride, vinylidene chloride or vinyl esters such as vinyl acetate, vinyl acetate homopolymers and copolymers, copolymers of styrene and unsaturated acid anydrides like maleic anhydrides, homopolymers and copolymers of acrylic and methacrylic acid and their esters and derivatives, polybutadiene, polyisoprene, butyl rubber, natural rubber, ethylene-propylene copolymers, olefins resins like polyethylene and polypropylene, polyvinyl alcohol, carboxylated natural and synthetic latexes, epoxies, epoxy esters and similar polymeric latex materials.

Latex paint compositions are well known in the art and typically comprise an emulsion, dispersion or suspension of discrete particles of resin binder and pigment in water. Optional ingredients typically include thickeners, antifoam agents, plasticizers, surfactants, coalescing agents, and the like.

These copolymers may include from about 0.1 to 5.0 weight % of ureido monomers to enhance wet adhesion properties as well as small amounts of hydroxy or carboxy monomers to assist copolymerization and to enhance adhesion. The ureido monomers are well known and are illustrated in U.S. Pat. Nos. 4,487,941 and 4,319,032. Similar adhesion promoters are known in U.S. Pat. Nos. 3,356,653 and 3,509,085.

These copolymers, except for the inclusion of the macromonomers which have been described, are entirely conventional. Similarly, the copolymerization in aqueous emulsion is also conventional or may be conducted using more sophisticated emulsion polymerization processing which is also known in the art such as core-shell or gradient morphology such that the monomer composition varies within the latex particles. Morphologies with soft cores and hard shells or hard cores and soft shells are possible including a change in the types of monomers used in the core and shell and throughout the gradient feeds. Most of these emulsion polymerization processes are normally conducted using a semibatch technique but are also possible in cycled continuous processing. Nonspherical particle morphology such as multilobe particles are also well known as possible using the monomers of this invention. The macromonomers can be utilized in a variety of ways during emulsion polymerization, e.g., in the monomer feed mixture or through staged feeds or power feed.

In an embodiment of this invention, the macromonomers can be made after the latex polymerization by reacting one or more complex hydrophobe compounds, e.g., surfactant, containing one or more functional groups with a complementary functional group on the surface of the latex or by reacting one or more complex hydrophobe compounds containing one or more complementary functional groups with a functional group on the surface of the latex. In particular, m-TMI or an anhydride such as maleic anhydride or an epoxide such as glycidyl methacrylate or glycidyl acrylates and the like, can be copolymerized with conventional emulsion polymerization monomers, preferably into the shell or surface of the latex particle. The resulting latex can then be heated in a surfactant solution until the surfactant reacts with the m-TMI or anhydride or epoxide on the surface of the latex.

In another embodiment, the macromonomer can be made in situ in the latex copolymerization process. For example, m-TMI and other unsaturated monomers can be polymerized in the presence of one or more complex hydrophobe compounds, e.g., surfactant, in the polymerization medium. Such a method can be conducted by conventional procedures.

As used herein, the term "complex hydrophobe" is contemplated to include all permissible hydrocarbon compounds having 2 or more hydrophobe groups, e.g., bis-dodecylphenyl, bis-nonylphenyl, bis-octylphenyl and the like.

For purposes of this invention, the term "hydrocarbon" is contemplated to include all permissible compounds having at least one hydrogen and one carbon atom. In a broad aspect, the permissible hydrocarbons include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, aromatic and nonaromatic organic compounds which can be substituted or unsubstituted.

As used herein, the term "substituted" is contemplated to include all permissible substituents of organic compounds unless otherwise indicated. In a broad aspect, the permissible substituents include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, aromatic and nonaromatic substituents of organic compounds. Illustrative substituents include, for example, alkyl, alkyloxy, aryl, aryloxy, hydroxy, hydroxyalkyl, amino, aminoalkyl, halogen and the like in which the number of carbons can range from 1 to about 20 or more, preferably from 1 to about 12. The permissible substituents can be one or more and the same or different for appropriate organic compounds. This invention is not intended to be limited in any manner by the permissible substituents of organic compounds.

The invention is illustrated by certain of the following examples.

EXAMPLE 1

Preparation of 1,3-Bis(nonylphenoxy)-2-propanol

To a five neck, two liter round bottom flask equipped with an addition funnel, thermometer, nitrogen dispersant tube, mechanical stirrer, and a decanting head with a water-cooled condenser were added 220 grams (1.00 mole) of nonylphenol and 250 milliliters of cyclohexane. The solution was then heated to reflux and 2.8 grams (1.3 wt. % based on nonylphenol) of potassium hydroxide in 10 milliliters of water was slowly added to the flask. After essentially all the water was recovered in the decanting head (10 milliliters+1 milliliter formed), 250.7 grams (0.91 mole) of nonylphenyl glycidyl ether as added dropwise. During the addition of the glycidyl ether, the reaction temperature was maintained between 60° and 80° C. After the addition was complete, the solution was refluxed for four hours. The contents of the flask were then washed with a five percent aqueous solution of phosphoric acid, and the organic layer was separated from the water layer and washed twice with deionized water. The reaction mixture was then placed in a one liter round bottom flask, and the remaining cyclohexane and unreacted nonylphenol were recovered by distillation, first at atmospheric pressure, then under vacuum at 0.2 mm Hg. The kettle temperature was not allowed to exceed 180° C. during the distillation to prevent discoloration of the product. The concentrated solution was then refiltered to give 425 grams of a pale-yellow liquid. End-group MW analysis gave a molecular weight of 506.8 (theoretical MW=496.8). Ir and nmr spectra were identical to previously recorded spectra for the compound.

EXAMPLE 2

To a five neck, two liter round bottom flask, equipped with an addition funnel, thermometer, nitrogen dispersant tube, mechanical stirrer, and a decanting head with a water-cooled condenser, were added 300 milliliters of cyclohexane and 451.7 grams (2.05 mole) of nonylphenol. The solution was then heated to reflux and 58.9 grams (1.05 mole) of potassium hydroxide in 60 milliliters of water was slowly added via the addition funnel. After essentially all the water was recovered in the decanting head (60 milliliter+19 milliliters formed), the reaction was cooled to 40° C., and 92.5 grams (1.00 mole) of epichlorohydrin was slowly added. During the addition, the reaction temperature was maintained below 60° C. by controlling the rate of epichlorohydrin addition. After all the epichlorohydrin was added, the solution was allowed to stir for one hour, and then brought to reflux for an additional three hours. The reaction mixture was then filtered under vacuum through a steam-jacketed Buchner funnel to remove the potassium chloride formed as a by-product. The filtration process was performed a total of three times to remove the majority of the salts. The reaction mixture was then placed in a one liter round bottom flask, and the remaining cyclohexane and unreacted nonylphenol were recovered by distillation, first at atmospheric pressure, then under vacuum at 0.2 mm Hg. The kettle temperature was not allowed to exceed 180° C. during the distillation to prevent discoloration of the product. The concentrated solution was then refiltered to give 275 grams of a pale-yellow liquid. End-group MW analysis gave a molecular weight of 459.7 (theoretical MW=496.8). Ir and nmr spectra were identical to previously recorded spectra for the compound.

After purging the reactor with nitrogen, the alcohol was heated to 130° C. with stirring, and 86.9 grams (2.0 mole) of ethylene oxide was added over a two hour period. The reaction temperature and pressure were maintained from 130° C. to 140° C. and 60 psig during the course of the reaction. After the addition of ethylene oxide was complete, the reaction mixture was held at 140° C. for an additional hour to allow all the ethylene oxide to cook out. The reaction mixture was dumped while hot, under nitrogen, and neutralized with acetic acid to yield 285 grams of a pale-yellow liquid.

EXAMPLE 4

Preparation of Adduct of Nonylphenyl Glycidyl Ether and 5Mole Ethoxylate of 1,3-Bis(nonylphenoxy)-2-propanol

To a five neck, one liter, round bottom flask equipped as in Example 1 was added 119.8 grams (0.17 mole) of the 5 mole ethoxylate of 1,3-bis(nonylphenoxy)-2-propanol and 100 milliliters of cyclohexane. The mixture was refluxed (100° C.) for one hour to remove residual water, and then cooled to 50° C. under nitrogen to add 0.5 grams of BF₃ /Et₂ O. Nonylphenyl glycidyl ether (46.0 grams, 0.17 mole) was then added to the flask over a one hour period, and the reaction was heated to reflux. After three hours at reflux, the reaction mixture was transferred to a separatory funnel, while hot, and washed with a saturated aqueous solution of sodium bicarbonate. The organic layer was separated from the water layer, and washed twice with hot deionized water. The washes were performed at 50° C. to facilitate the separation of the two layers. The water and cyclohexane were then evaporated from the organic layer, under vacuum, to yield 145 grams of a pale-yellow, viscous liquid. End-group molecular weight analysis gave a molecular weight of 880 (theoretical molecular weight=993).

The vessel was attached to an automated ethoxylation unit and was heated to 50° C. The vessel was continuously purged with nitrogen for 15 minutes and was then heated to 100° C. where it was again continuously purged with nitrogen for another 15 minutes. The vessel was then heated to 140° C. and was given a series of 6 purges by pressuring the vessel up to 80 psi, and then venting. Once the venting process was complete, the vessel was pressured to 20 psi with nitrogen.

The ethylene oxide lines were opened to the motor valves along with the main feed line on the Zipperclave. The feed was continued and the vessel pressure was regulated at 55 psi and a temperature of 140° C.

The reaction mixture was then placed in a one liter round bottom flask, and the remaining cyclohexane and unreacted nonylphenol were recovered by distillation, first at atmospheric pressure, then under vacuum at 0.2 mm Hg. The kettle temperature was not allowed to exceed 180° C. during the distillation to prevent discoloration of the product. The concentrated solution was then refiltered to give 710 grams of a pale-yellow liquid. Molecular weight by end-group MW analysis was 689.9 (theoretical MW=643.0). Ir and nmr spectra were consistent with the expected structure of the product.

EXAMPLE 17

Preparation of Macromonomer Compound

Into a 1 liter round bottom reaction flask equipped with a heating mantle, dean stark trap, condenser, thermometer, nitrogen bubbler, nitrogen purge line and stirrer was charged 300 grams of toluene and 63 grams of a surfactant identified as S-1 in Table A below. With nitrogen purge, the resulting solution was heated to reflux at approximately 110° C. and azeotroped to remove trace water to dryness. The solution was subsequently cooled to 90° C., and 1.5 grams of bismuth hex chem 28% bismuth octoate catalyst (Mooney Chemical, Inc., Cleveland, Ohio) was charged and allowed to mix well, after which a stoichiometric amount of 95% m-TMI aliphatic isocyanate (American Cyanamid, Stamford, Conn.) was charged. After the reaction proceeded at 90° C. for 1.3 hours, the resulting product was cooled to 70° C. and 0.03 grams of 2,6-di-tert-4-methyl phenol (BHT) preservative was added. The mixture was poured into a stainless steel pan with large surface area to facilitate drying. The final product was a waxy material, and is designated herein as macromonomer M-1.
